Ways to Reduce Power Consumption on Mobile Monitors in the High Efficiency Video Coding Standard

Power consumption of mobile screens of laptops, tablets and mobile phones, due to their limited battery capacity, is one of the problems that users of these devices face. Some new hardware technologies, such as dynamic voltage and frequency scaling (DVFS), have reduced the consumption of these displays in some cases, but there are still many problems with DVFS. The High Efficiency Video Coding (HEVC) Standard is the latest and most useful video compression method used for high quality video capture and display in formats such as ۴K and ۸K. With all the advantages of HEVC, one of its disadvantages is the high power consumption when encrypting and decrypting videos, which should be minimized by providing solutions. In this paper, the latest methods in reducing power consumption in mobile monitors are reviewed and compared, and suggestions for its improvement are presented. Reducing power consumption in these methods sometimes reaches to ۲۰ nj/px for video formats.
